{ "error": { "message": "(#131058) Hello World templates can only be sent from the Public Test Numbers", "type": "OAuthException", "code": 131058, "fbtrace_id": "AfnikW3U6xSnezttS2D_k-x" } }

Can anyone tell me why the above error is happening? It was working before now i'm just getting this error.
